All tests were run under Windows 7 Ultimate (BootCamp) on a 2010 Mac Pro tower 6-core 3.33GHz.

Tomb RaiderUsing "Ultra" preset, we ran the built-in benchmark. (HIGHEST in Average Frames per Second = FASTEST)

Left 4 Dead 2
We use the console command "timedemo" to playback a recorded game session. Settings were Fullscreen, 8X AA, Anisotropic 16X, Vsync Disabled, Shader Detail Very High, Effect Detail and Model/Texture Detail both High, Multicore Rendering Enabled. (HIGHEST in Average Frames per Second = FASTEST)

Diablo III(Patch 2.4.1)
My character is standing next to the New Tristram Waypoint. Settings were Fullscreen, AA enabled, Reflections DISabled, all other settings "HIGH." (HIGHEST in Average Frames per Second = FASTEST)

World of Warcraft: Warlords of Draener
Our character is standing at the entrance to the Dark Portal watching the forming crowd assault each other. Settings were Fullscreen, Ultra Preset, Anti-Aliasing = SSAA4x. Average FPS was calculated by Titan Performance Addon. (HIGHEST in Average Frames per Second = FASTEST)

DaVinci Resolve 12.5 Studio
Using the Candle Benchmark Project, we performed a "render on the fly" playback using 3 nodes of Noise Reduction, a GPU intensive function. (The GTX 1080 was not recognized by the CUDA driver as a CUDA capable GPU so its slower result below is using OpenCL.) HIGHEST in Average Frames per Second = FASTEST

ANALYSIS
This was our initial test session with the GeForce GTX 1080. In the tests featured above, it is 55% to 83% faster than the GTX 980. Though the GTX 1080's advantage over the 980 Ti and TITAN X is less pronounced, it is still faster than both (except for DR test with caveat) while requiring much less power than either.

Once there is a CUDA driver that recognizes the GTX 1080, we will post some CUDA benchmarks including Blender and Octane Render.

And, yes, the GTX 1070 is on our "to do" list.

We hope there will soon be a web driver that will allow the GTX 1080 to be run under OS X.

BIG MAHALO to MacVidCards for the loan of the GTX 980 and TITAN X Hybrid.
